Custom Shop KW901 Automotive Wax & Grease Remover, 1 Gallon — Fast‑Drying, Low‑Residue Panel Wipe

Custom Shop KW901 is a concentrated grease and wax remover formulated to quickly dissolve surface contaminants so painted panels and parts are left residue-free and ready for painting or refinishing.

When prepping automotive panels for paint, adhesion depends on a genuinely clean surface — not just a visually clean one. KW901 targets common film-forming contaminants like wax, tar, adhesive residue, tree sap, silicones and light oils, loosening and lifting them so they can be wiped away without smearing. This one-gallon formulation is designed for professional and enthusiast shops that need an efficient, low-residue panel wipe before bodywork, sanding and topcoat application.

How does KW901 remove wax, grease and similar contaminants?

KW901 uses a fast-acting solvent blend that penetrates and breaks the bond between contaminants and the substrate. After applying with a lint-free cloth, the dissolved material lifts from the surface and can be removed with a second clean cloth, leaving minimal residue and a clean surface for paint adhesion.

• Solvent formula designed to dissolve wax, tar, adhesives and silicones.
• Applied with a wet cloth and removed with a separate dry cloth for best results.
• Dries quickly to minimize recontamination and speed up workflow.

What surfaces and prep steps are appropriate for this cleaner?

KW901 is safe for most automotive substrates when used as directed, including painted metal, plastic, epoxy and fiberglass. It is ideal before and after sanding operations and works as an anti-static, anti-silicone panel wipe prior to primer or topcoat application.

• Suitable for painted panels, bare metal, plastic trims, epoxy and fiberglass.
• Recommended as a final wipe after sanding and before primer/topcoat.
• Use two separate lint-free cloths: one for application, one for removal.

How do I use the one-gallon KW901 safely and effectively in my shop?

Pour or decant a small amount into a trigger bottle or use directly from the can for larger panels. Apply sparingly with a clean lint-free cloth, working section by section, and immediately follow with a second cloth to remove dissolved residues. Ensure good ventilation and follow standard solvent handling practices.

• Work in a well-ventilated area and wear appropriate gloves and eye protection.
• Use a separate wet cloth and a separate removal cloth to avoid re-depositing contaminants.
• Store the one-gallon can upright, tightly sealed, away from heat sources.
